Description
Invention field
The present invention relates to low-temperature refrigeration technology, particularly a kind of deep cooling warm area (multicomponent mixture working medium throttling refrigerant of 100～150K) that is applicable to.
Background technology
According to the low temperature thermodynamic theory, overlapping and backheat are to realize two possible methods of cryogenic refrigeration.Realize the necessary high generalized force of low temperature by utilizing overlapping or backheat to reduce.Mixing medium is applied in the circulation of back-heating type throttling refrigeration, can reduce operating pressure greatly, reduce throttling process and heat recovery process loss, improves system efficiency.The system schematic of mixing medium back-heating type j-t refrigerator is seen Fig. 1; mainly constitute by compressor CP, water cooler AC, counter flow back-heating interchanger HX, throttling element JT and cryogenic vaporizer EV; sometimes in order to consider measures such as oil return; can on the parts of bearing the backheat effect, do some variations; constitute interior overlapping circulation form, see Fig. 2 with vapour liquid separator.The composition of mixed work medium for throttling refrigeration agent is closely-related with the form of the construction system of realizing refrigerating hardware and these hardware, but shows through further investigation, and the mixing medium proper property is the basic factor of decision performance of refrigerant systems.After further research, the selection principle of mixing medium in various refrigeration systems all can be considered from the following aspects:
The one, guarantee that mixture can reach required low temperature in the operating pressure scope; the 2nd, guarantee that irreversible loss is reduced to minimum in the refrigeration cycle process; the 3rd, guarantee that mixing medium meets relevant environmental regulations; and have good physics, chemical stability, and other are such as the source and the consideration of economy etc.
Still there is not at present the mixing medium patent that directly applies to this warm area.Existing technology such as U.S. Pat 5,441,658 and China patent CN97,115,295.0 all to be applied to liquid nitrogen temperature (80K) be main purpose.Wherein, United States Patent (USP) has provided fixedly melting concn component, is applied to liquid nitrogen temperature, finds through further investigation, and the given mixing medium thermo-efficiency of this patent is still not high enough.Therefore, we have proposed a kind of mixing medium refrigeration agent that is applicable to cold zone on the further investigation basis, patent CN97115295.0, its main purpose is further to improve the thermo-efficiency of mixed work medium for throttling refrigeration agent, and reduce the combustibility of refrigeration agent, obtain low-temperature mixed throttling refrigeration agent efficiently, this technology is an application target with the 80K warm area still.
Find out that thus the given mixing medium refrigerant applications target of prior art is the low temperature field, mainly at liquid nitrogen temperature (80K).If be applied in more than the liquid nitrogen temperature (80K), efficient will descend.Here need to mention a bit: at patent CN97, in the definition to refrigeration thermo-efficiency in 115,295.0, what the calculating of relevant compression process wasted work was adopted is isothermal compression, and for refrigerating industry totally-enclosed compressor commonly used, wherein the compression process of Fa Shenging in fact more approaches adiabatic compression.The adiabatic compression wasted work is bigger than isothermal compression wasted work, and has only considered the working medium natural characteristics among the embodiment that provides of this patent, and the pressure condition that provides is not suitable for single-stage compressor operation condition (pressure ratio is too high, has 25).For the working medium that becomes with a kind of known group, the thermo-efficiency that adopts the adiabatic compression wasted work to calculate is littler by 15%～25% than adopting the isothermal compression counting yield.
In sum, prior art mainly is the mixing medium that proposes at liquid nitrogen temperature, and current research shows, its effective temperature range of operation of frozen composition multicomponent mixture work medium is narrower, generally about 5～15K, exceed this scope then efficient sharply descend.Therefore, the mixture working medium of liquid nitrogen temperature can not operate in the above warm area of 100K efficiently, and prior art does not take into full account practical factors such as concrete compressor operating operating mode in addition.
Summary of the invention
The object of the present invention is to provide a kind of deep cooling warm area (efficient multicomponent mixture working medium throttling refrigerant of 100～150K) that is applicable to.Compared with the prior art, it is higher that the mixing medium that the present invention proposes is suitable for warm area, and taking into full account the suitable operation pressure ratio operating mode of single-stage compressor aspect the concrete concentration proportioning, and at providing its corresponding concentration range every 10K in 100～150K warm area.
The foundation of carrying out the warm area division is on the mixing medium inherent thermodynamic property, in the mixture of certain known concrete composition, each composition is brought into play not same-action at the refrigerator operation temperature area to different warm areas between the envrionment temperature in the mixture, but every kind of constituent element is only brought into play effective refrigeration at a relatively-stationary warm area, and bring into play less effect at other warm areas, thus, can be desirably in the mixture and form similar a kind of relay effect by the cooperation between each constituent element, realization to the efficient combination the required refrigeration temperature, is seen Fig. 3 from envrionment temperature.
The mixture throttling refrigerating machine building block is simple relatively, corresponding to different parts generations are different thermal processing, referring to Fig. 4, be included in the adiabatic compression of carrying out in the compressor, isobaric heat release in the water cooler, heat recovery process in the Recuperative heat exchanger, throttling expansion process in the throttling element, this is the process that realizes energy transformation, merit by the compressor input is converted to cold fire usefulness, in vaporizer, realize the utilization of cold fire usefulness, low-pressure low-temperature working medium enters Recuperative heat exchanger cooling high pressure incoming flow working medium, after self temperature returns to envrionment temperature, enters compressor and finishes a thermodynamic cycle.Therefore, mixing medium finally will be embodied in influence to above-mentioned several thermal processing to the refrigerator Effect on Performance.In addition, the status of different thermal processing in refrigerator is also not quite identical, wherein heat recovery process is to influence (when especially the adopting multicomponent mixture working medium) maximum of refrigerator, the effect of heat recovery process also has a significant impact throttling process simultaneously, be in particular in when backheat is improved, temperature reduces before causing throttling, and the loss of throttling process is also reduced greatly.Therefore mixture working medium being selected to take all factors into consideration influence to each thermal processing, is that the irreversible loss of each process is reduced for preferred working medium, and final system obtains optimum performance.
According to above-mentioned analysis, be the calculating principle of example explanation mixed work medium for throttling refrigeration cycle thermal performance with Fig. 1, working cycle shown in Figure 4:
